To all whom it may concern.' y

Be it known that l, JULIUs Kennen, a

vcitizen of. the United States, and resident 0f lVest Bend, in thecounty of Washing- Lton and State of Wisconsin, have invented certainnew and useful Improvements in Pasteurizers; and I dov hereby declarethat the following is a full, clear, and exact description thereof.

My invention `consists in what is 'herein particularly set forth withreference to the accompanying drawings and pointed out in the clam ofthis specification, its object being to provide simple, economical andefficient pasteurizing apparatus especially designed for the treatmentof bottled` beer and having the advantages subsequently specified.

Figure 1 of the drawings represents a side elevation of a pasteurizingapparatus in accordance with my invention partly broken away; Fig. 2, avertical section of the same longitudinally thereof, the section beingindicated by line'` 2 2 in Fig. 4; Fig. 3, a plan View of said apparatuscontracted and partly in horizontal section indicated by line 3-3 inFig. 2, and Fig. 4, a cross-secion gf the same indicated by line 4-4 inReferring by numerals to the drawings, 5 indicates a. rectangularcovered tank rest-- ing on sills 6, and rising from the bottom of thetank to a predetermined height are transverse partitions 7 by which saidtankl is divided into three water compartments, each having an overflowoutlet 8. J ournaled in side bearings of the tank'a'bove the water levelof its compartments are a series of parallel transverse preferablywooden roll-- ers 9 at suitable intervals apart, and fast onone journalof each roller, outside of said tank is a worm-wheel 10 in mesh with oneof a series of worms 11 on a driven shaft 12 for which the ends of agear-casing 13 is provided with bearings, said rollers copstituti'ng aconveyer for steaming trays 14 in which the bottle goods to bepasteurized are carried, the bottom of the trays being perforated. Theloaded trays are fed to the conveyer through an opening in one end ofthe tank and discharged through an opening in the opposite end of saidtank, as indicated in Fig. 2, and, as indicated in Fig. 4, `the width ofthe ap' paratus is such that two parallel series of said trays may beoperated upon at the same time,- o r said apparatus may be indefinitelywidened to increase its capacity. Supported in the tank, above the `endJopenings'therein for the loaded trays, are

pans 15, 15', 15 having perforated bottoms and corresponding in numberto the aforesaid water compartments with which they register, and inFig. 4, the tank-cover is shown provided with a manhole having a`closure 16.

Reading from the left of Fig. 1, a centrifugal pump 17 in connectionwith the first water compartment of the tank discharges through a pipe18 into the pan 15and a similar pump 19 in connection with the thirdwater compartment of said tank discharges through a. pipe 20 into thepan 15. Another centrifugal pump 21 -in connection with the middlecompartment of thetank discharges through a pipe 22 into the middle pan15 and a horizontal pipe 23 connects the lirstv and thirdwatercompartments of said tank.

A single shaft 24 is shown common to all the pumps, said shaft beinpreferably that of an electric-motor 25. sprocket-wheel v26 is shownfast on the shaft 24 and connected by a link-belt 27 with a similarwheel 28 fast on the worm-shaft. y

A steam-discharge pipe 29 is shown extending into the middlewater-compartment of the tank to thus provide for heatin of the contentsof Vsaid compartment, an a similar pipe 30 is shown leading into thefront end compartment of said tank to provide for heating the contentsthereof.

In practice. the water in the first and third compartments of the tank(connected by the pipe 23) is of equalized temperature lower than thewater in the intermediate compartment of said tank. The loaded trays aretraveled slowly by the rollerv conveyer in the direction indicated by anarrow in Fig. 1, under the several pans aforesaid to effect a warming,pasteurizing and cooling of the bottled goods in said trays withoutsubmergence of the same. i

A pasteuri'zing apparatus comprisingl a. rectangular coveredtank havingopposite end openings, transverse partitions rising from the bottom ofthe tank to divide the same into three compartments, 'a series ofparallel rollers arranged in the tank transversely of the same betweensaid end openings, means for simultaneously driving all Patented Feb. 9,1915.

the rollers in the same direction, whereby provision is had forconveying steamingcompartment; and means for circulating the 04attemperated Water from each of said compertinents through the pan inregister therewith.

ln testimony that l claim the foregoing li have hereunto set my hand atWest Bends in the county of Washington and State of Wisconsin, -n thepresence of two Witnesses. 20
